What is Service B at Mercedes-Benz?
The Mercedes-Benz B Service is a major manufacturer's overhaul. It is scheduled to be carried out regularly according to a clearly defined interval set by the brand:
Every 32,000 km or every 2 years , whichever comes first.
Unlike Service A, which is a lighter service, Service B is more comprehensive, more thorough, and includes more checks and replacements . It aims to ensure driver safety, protect the Mercedes engine, and guarantee optimal performance.
When should Service B be performed?
Mercedes makes life easier for drivers thanks to the ASSYST PLUS system integrated into the dashboard.
This system:
-
Analyze your driving habits
-
Takes into account real-world usage conditions (climate, journeys, traffic, etc.)
-
Automatically notifies you when a revision is needed
Thus, the maintenance indicator will usually appear when approaching 2 years or 32,000 km traveled .
It is recommended not to delay the appointment, as this may affect the manufacturer's warranty and lead to premature wear.
What the Mercedes-Benz B Service includes
The exact program may vary depending on the model (A-Class, C-Class, E-Class, S-Class, CLA, GLA, GLC, GLE, etc.), year, engine and AMG packages.
